Les Dirouilles (Jèrriais: Les Dithouïl'yes) are a range of rocks to the North-East of Jersey. Jèrriais is a form of Norman language spoken in Jersey in the Channel Islands. ...
They have a large range of names, taken individually, and are also known as just Les Pièrres (the rocks).
All of these except Jersey are in the Bailiwick of Guernsey, but the Minquiers and Ecréhous as well as the LesDirouilles and Les Pierres de Lecq (the Paternosters), uninhabited groups of islets, are part of the Bailiwick of Jersey.
As a general rule, the larger islands have the -ey suffix, and the smaller ones have the -hou suffix; this is believed to be from the Old Norse ey and holmr respectively.
Among these are Ouessant/Ushant, Bréhat, Île de Batz, and Îles Saint-Marcouf (under French jurisdiction), and the Isle of Wight, and Isles of Scilly (under UK jurisdiction).
